1. INTRODUCTION
The wireless mesh networking is used to monitor the
environmental issues. It has the advantage of imposing no
issues due to cabling of data transmission. Wireless mesh
network consist of more than one node and it has combined
multiple transceiver to co-operatively transmit and depend
their data thereby the range of communication can be
extended.
The WSN generally consist of large number of low cost and
power multi functional sensor nodes. In Wireless sensor
network, the different nodes are communicated with each
other wirelessly over a short distance and those capable of
organizing themselves in an autonomous multi hop network.
WSN system also has been used in many applications such
as, health monitoring, environmental monitoring and
agricultural monitoring. Wireless sensor network unable for
environment monitoring of large areas with so many
wireless sensors. Therefore in many of the paper they
combined the characteristics of WSN for the formation of
mesh network. In WSN, there is sink as master node and
multiple slave nodes are connected with each other for the
formation of mesh network.
In this we described, combines various nodes and form a
network that regularly sense and may control after
monitoring data. The main objective of developing such
system, that formation of wireless mesh network design,
and adjust the topology according to the changes of radio
interference
obstacles, transfers the various sensors data back to the sink
and upload the data from sensors at regular intervals. We
design WMN module, which can be integrate easily with
sensor system for extending the communication range as
well as reduce the interference between them.
In this module we used Pro Zigbee model, it is one of the
most popular design which supports wireless mesh
networking module which is based on the IEEE standard
802.15.4. Zigbee is used as the wireless communication unit
with various sensor nodes and Pro-Zigbee protocol is
selected because it has low cost and low power wireless
communication protocol.

The silent feature of Pro Zigbee module is as follows
 Power output is 63mW
 Indoor Range is upto 90meters
 Outdoor range/Line of sight range is upto 1.6Km

 RF data rates is upto 250Kbps
 Interface data rate is upto 115.2Kbps
 Operating frequency is 2.4Ghz, because operating on
ISM band
 Receiver sensitivity is -100dBm.
They design wireless module which are easy to configure
with system and it’s suitable for point to point, point to
multipoint network and also compatible with mesh network.
The various sensor nodes in WSN consist, main processor,
data aquaization unit, memory unit to stored the data and
different sensors.
In our paper, we use one master node and three slave nodes
for the different monitoring application such as agricultural,
industry and monitor power of any type of circuit. For that
purpose we use ATMEGA16 processor for master node and
for slave node we use ATMEGA8 processor. We can collect
the data at any instant of time from any nodes and that data
can easily stored in main processing unit. In survey we can
clearly seen that many authors, worked on open source
module which is compatible for both hardware and software.
But we can also be used to study the performance of WMN
on real time base parameters and that we are shown in future
scope.
2.1 ARCHITECTURE OF WMN
In wireless mesh networking we use various sensor nodes
for the monitoring of various application such as industrial,
agricultural and power measurements of given that means
we can measure the current and voltage. The WMN module
can design using 8 bit controller based on AVR enhanced
RISC architecture, ATMEGA16 is low power CMOS 8 bit
controller with low cost RF transmitter and receiver circuit
in which output power is nearly equal to 1mW at 2.4GHz.

The primary stage to design such model is connecting
ATMEGA16 to main processor and that main processor
interface the control signal and transfers the data in terms of
packets to main processor. In this, the main processor only
deals with ATMEGA16 8 bit microcontroller whenever the
data packets send or receive. The main processor does not
need to worry about the various nodes that are connected
through this controller.

2.2 DESIGN OF WSN MODULE
A WSN is the combination of, various hardware sensors,
combines sensing, computation and communication for
monitoring and recording conditions at diverse location.
Wireless network consist of various sensor nodes which are
used to detect or sense the data. The parameters that are
commonly and regularly monitored such as temperature,
humidity, pressure, sound intensity, gas, voltage, power, soil
and many other applications.

A WSN consists of multiple stations in given region called
as sensor nodes. The size of sensor node is very small,
lightweight and it’s portable. The sensor nodes are
connected to the user through internet and the master node
2.3 TRANSMITTER NODE

Each transmitting nodes consist of one ATMEGA 8
microcontroller with Zigbee wireless module and various
sensors such as temperature sensor, Gas sensor, smoke
detector sensor and LDR sensor.
2.4 FORMATION OF MESH NETWORK
In our proposed system, we use total four nodes including
master node for various applications. Each sensor node of
the system having identification number assigned to it. And
each nodes has corresponding timeslot in every TDMA
cycle, to avoid the different sensor nodes try to transmit the
data at same timeslot. When the formation of mesh network,
use master node as Sink node and other node act as sensor
node. Master node assigned the unique identificatiob
number as ID 0 functioned as Sink. And the other nodes
which identificatib number is not zero are sensor nodes
which sense the data and transfer to sink node.

4. CONCLUSION
There are so many papers on environmental monitoring
using wireless sensor network. But in this paper we used
more than one application for monitoring. We make mesh
module in that different wireless sensors are combinly used
to transmit the data to main node at every time without fail.
We not only monitored the different fields but also control
them if they cross the threshold level of particular sensor.
For that purpose we provide a relay and buzzer, which
indicates threshold level crossed and we provide relay in
each system to control the application. If any of the node is
fail in mesh topology then their data is stored as backup to
its neighboring node.
So according to this we can monitor environmental
application as well as control the appliances that are
connected as sensor.
